Abstract: RESILIENT DETENTED LID LATCH          ABSTRACT OF THE DISCLOSURE         A latch unit for releasably securing a plastic lid to a tank-like container or for releasably securing another covering over the container.  The container may be the tank of an electric vacuum cleaner.  There are a plurality of the latch units spaced along the edge of the lid or covering and engageable with a bead around the open end of the tank.  Each latch unit includes a cage at the edge of the lid or of the covering and includes a latch element molded of resilient plastic material.  One end of the latch element protrudes from the cage and is hand engageable for moving the element between releasing and holding positions.  The other end of the element is provided with a hook that engages a cage formation to form a pivot for the element.  A normally bowed intermediate section of the element connects opposite ends of the element, and is stressed to provide a biasing force that holds the element mounted to the cage.  This biasing force also provides detent forces required to maintain the latch element in the holding or releasing position to which it is operated.  A detent at the intermediate section of the element engages an upstanding wall of the cage to hold the element in the releasing position.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed are carboxylic acid containing polymeric microgel particles which are prepared by polymerizing in aqueous emulsion a monomer mixture containing about 10-50% by weight of polymerizable carboxylic acid monomers, up to 5% of a difunc-tional crosslinking monomer and one or more carboxyl-free relatively water insoluble polymerizable vinyl monomers.  The resulting microgel particles are water-swellable and may be employed as stabilizers for use in the preparation of aqueous dispersions of film-forming resins containing smaller amounts of organic solvents than conventional aqueous dispersions of this type.  Such dispersions are useful as coating compositions, yielding coatings having less water sensitivity and improved adhesion as compared with coatings obtained from conventional aqueous dispersions of film-forming resins.

Abstract: Abstract of the Disclosure It is known to use a pyrometer system for measuring the temperature of blades of a gas-turbine engine, in which a high-resolution radiation pyrometer supplies signals to a detector unit.  In the present invention the detector unit includes an inverter that inverts the pyrometer output and supplies these signals via a diode to one electrode of a capacitor.  The other electrode of the capacitor is grounded, a resistor being connected across the capacitor so that it is slowly discharged.  The charge on the capacitor approximately follows the high-value/low-temperature signals which are reinverted to give an averaged temperature indication.  The diode is short-circuited for periods approximately equal to the time of passage of one blade across the pyrometer's field of view and at a frequency approximately equal to the blade rotational frequency.  During these periods the charge on the capacitor drops to the instantaneous value of the pyrometer output, producing a low-voltage/high-temperature spike.  The detector unit includes a store to which these spikes are supplied after reinversion.  The store has a long time period so as to produce a signal which approximately follows the tips of the high temperature spikes.

Abstract: Abstract of the Disclosure A  transducer  for  converting  an  electrical current signal to a pneumatic pressure.  A solid state element such as peizo-electric flapper element 48 is used to vary the pressure drop through a nozzle 46 to provide a  controlled  pressure  supply  28.    A  micro-power electronic circuit 59 controls the flapper.   A solid state pressure sensor 24 detests the output pressure and provides a feedback signal for use in a negative feedback loop to control the flapper element.  The flapper element may be triangularly shaped to reduce its responsiveness to relatively low frequency mechanical vibrations.  In a exemplary embodiment,  where  intrinsic safety  require-ments limit terminal voltages,  the flapper element is driven  by  a  transconductance  amplifier  94  which  is powered  through  a  shunt  regulator  82 and  a  voltage tripper  92.   The  shunt  regulator  provides  operating potentials which are derived from the signal current.

Abstract: ABSTRACT OF THE DISCLOSURE      A first piston 20 is cocked by applying pressure to a chamber 17 in the front end of a cylinder 10, which attendantly compresses a first spring 70.  Upon subsequently releasing a trigger latch 82, the spring 70 drives an injection needle 31 carried by the rod 22 of the piston into a tree trunk.  Pressure is next applied to a space 45 behind a second piston 40 slideable within the first piston skirt, which zero volumes a chamber 21 between the two pistons and compresses a second spring 71.  The space 45 is then vented, whereupon the spring 71 separates the two piston heads to vacuum fill the reestablished chamber 21 with a vascular treatment liquid for trees.  Finally, the space 45 is re-pressurized to force the liquid into the tree through the inserted needle.

Abstract: IMPROVED MULTIPULSE LPC SPEECH PROCESSING                 ARRANGMENT            Abstract A speech pattern predictive coding arrangement includes forming a prescribed format multipulse excitation signal for each successive time frame of the pattern.  The multipulse excitation signal corresponds to the frame predictive residual.  The redundancy in the multipulse excitation signal is reduced by forming a signal representative of the similarities between the current frame speech pattern and the speech pattern of preceding frames and removing such similarities from the multipulse excitation signal.  Advantageously, the bit rate of the multipulse excitation signal is reduced and the excitation signal is rendered substantially independent of voice pitch.
